3 Claims.

The invention relates to a windshield and more particularly to a rotating vision disk for vehicular Windshields.

The primary object of the invention isthe provision of a device of this character, wherein through the use of rotatable glass disks vision can be had through a windshield during inclement weather and in association with such disks are wipers which maintain the disks clean or clear particularly'from ice, sleet and rain.

Another object of the invention is the provision of a device of this character, wherein the rotating vision disks operate within wells or fonts which contain anti-freeze solution, so that ice and sleet will be prevented from forming on thedisks and also through associated wipers the said disks will be maintained clear; and clean.

A further object of the invention is the'provlsion of a device of this character, wherein clear effective in operatiomstrong, durable, and inex- Y pensive to manufacture and install.

With these and other objects in view, theinvention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention t and pointed out in the claims hereunto appended. I

In the accompanying drawing: K

Figure 1 is an elevation of a windshield show ing the device constructed in accordance'with the invention applied thereto. I l Figure 2 is a vertical sectional viewshowing one of the rotatable disks in elevation.

Figure 3' is a top plan view of the structure shown in Figure 2.

Similar -reference characters indicate corre-.

sponding parts throughout the several views in the drawing. Y

Referring to the drawing in detail, A designates generally a windshield glass which as usual is set.

in a frame B and the same rises from a dash or instrument boardC within a vehicle, in this instance the dash or-board being of special construction to accommodate spaced vertically arranged substantially half circular housings l0 preferably made of metal and each constitutes a well or font ll. Accommodated within the 5 wells of these housings H) are the lower halves of rotatable glass disks II which are of a thickness corresponding to the glassA and are accommodated at their upper halves in similarly shaped recesses provided in said glass A, these disks I2 1 at the ,centers thereof are hired upon the power shafts of electric motors l3 so that said disks can be driven and in the driving are rotated in reverse directions to each other. The. disks are spaced apart and are 80 disposed in the wind- 15 shield to give occupants of the front seat for-.- ward vision or clear vision ahead, particularly the operator of the vehicle. v

The motors l3 are made secure at H to the dash or board C. 20

Adapted to be contained within each well It is an anti-freeze solution (not shown), the houslugs "I at thev bottoms or lowermost points thereof being fitted with removable drain plugs to so that such solution as contained .within the well can be readily discharged therefrom. I

Encircling the upper half of the disk I2 at the outer periphery thereof is a substantially U- shaped weather stripping 16 which overlaps the edge of the opening-or recess throughout the 30 upper half of the said disk and also the said 7 disk so as to render the gap therebetwee'n weather-proof. Q

-At opposite sides of each disk I2 and mounted at the top of the companion housing l0 therefor 35 are stationary wipers II which .play upon'the opposite faces of the disks during rotationfor the wiping thereof, these wipers being fixed in [place by fasteners 18. M d Each housing at its topds' provided with a 4 a removable filler plug I 9 for the introductiomof anti-freeze solutioninto the' well'l l, the topof said housing being formed with an opening 20' for accommodating the disk I! companion thereto 1 I lated with each housing III are down- 3 wardly extending drain pipes 2| which discharge water from opposite faces of the disk I: as removed therefrom by the wipers ll during the erotation of said disk and thus exclude water 50 from within the well 'll constituted by the housins l0.

The disk I! when rotated travels within the anti-freeze solution contained within the wells ll within the housings l0 so that the opposite 66 iaces to! the disks will a very slight he placed within the wells II for the cleaning of the disks, this being eflected byrotating suchdisks for a determined period. in winter weather the anti-freeze solution is used and there is prevented ice, sleet and rain depositing upon the disks as by the rotation thereof the wipers I] will cleanthe same andthrough the use of the anti-freeze solution the formation 01' ice and sleet upon such disk will be avoided.

2Q In the use of the disks i2 clearvision is Y assured through the windshield.
